Abstract

A device for limiting a field on which radiation is irradiated, where thin aperture blades can be arranged in the device and where the aperture blades are highly accurately driven to enable a field on which radiation is irradiated to be highly accurately formed. A device (100) for limiting a field on which radiation is irradiated has aperture blades (20) arranged in the thickness direction, a flexible linear member (3) fixed to a thickness section of the aperture blades (20), a drive section (10) for driving the linear member (3) by a predetermined amount, and other components. One end of the linear member (3) is fixed, via a joining section (4), in the tangential direction along a circular arc on the outer periphery side of an aperture blade (20A), and the other end is joined to a moving element (15) received in a drive section (10). The moving element (15) is connected to a drive source (12) through a connection section (13) and moves in the direction of the axis of the drive shaft (14) as the drive shaft (14) inserted in a base (11) rotates. A load caused by the movement of the moving element (15) is directly transmitted to the linear member (3), and on receiving the load, the aperture blades (20) are driven by a predetermined amount.
